Terahertz imaging and spectroscopy has been shown to have the potential to use very low levels of this non-ionising radiation to detect and identify objects hidden under clothing at stand-off distances. In this paper we discuss some of the important factors involved in developing systems for the security industry, and describe our recent work on the development of a prototype terahertz stand-off detection system. Using this system we demonstrate the spectroscopic detection of concealed explosives at a stand-off distance of 1 m, both real time, in reflection, and under normal atmospheric conditions. We believe the technique has the potential for further development towards a practical system for the detection of suicide bombers and mobile subjects.
